Blizzard released a new unit at the Wrath of the Lich King Bestiary page: The Shovel Tusk.
The powerful and ferocious shovel tusks are easily identified by the massive curved antler which protrudes from their heads and the twin sloping tusks that extend from their jaw. The moose-like beasts use their tusks primarily to dig for food, whereas the antler makes for a fearsome ramming weapon in contests to establish dominance over other males.
The shovel tusks are territorial and will protect their feeding grounds with deadly force. Adventurers traveling in Northrend would be wise to avoid these cantankerous and unpredictable beasts.
